ZQuiet's main offer is 15% off your first order with the featured code at the top of this page—perfect if you're ordering for the first time and want an immediate discount on your initial purchase. However, the brand also runs several ongoing deals, so the right choice depends on what you're buying and how much you're spending.
For your first ZQuiet purchase under $25: Use the 15% off first order code. This saves you more than the free shipping options available and gets you straight into the brand without any minimum spend requirement.
For your first purchase between $25 and $50: You still have a choice. The 15% off first order code applies to your entire basket, while you'd also qualify for free shipping on orders over $25. Calculate what saves more: 15% of your total, or the cost of shipping. On smaller baskets in this range, the code will typically save you more.
For your first purchase over $50: Compare the 15% off code against the free shipping offer for all orders over $50. Since both apply to first orders, work out which delivers the larger discount. On a $75 order, for example, 15% off saves you $11.25, while free shipping might save less or more depending on the shipping cost. Check at checkout to see which is bigger.
For repeat customers buying mouthpieces: The Labor Day buy one, get one 50% off deal is running until September 8, 2026, and beats the 15% code if you're stocking up on multiple pieces. This deal applies automatically at checkout.
For repeat customers buying Ozlo Sleepbuds: The current 21% sale on this product is a solid saving. This applies automatically and saves you more than the standard 15% code.
For any order over $50: You'll qualify for free shipping on all orders, which stacks with other deals and lowers your total cost.
Only one promotional offer applies at checkout, so compare what's available in your basket and go with whichever saves you the most. Enter the first order code if you're a new customer, or let any running product sales and shipping deals apply automatically to your cart.
